ABSTRACT:
The invention provides an electrode for a lead-acid battery, formed in an essentially continuous process without the need for curing under controlled temperature and humidity conditions. This is accomplished by using a relatively high metallic lead content precursor powder intermingled with a leady-oxide powder. Another aspect of the invention is the use of relatively high surface area leady-oxide powder which contributes to performance. Another important aspect of the invention is that the active material paste is prepared without the use of an acid in a water based process which provides a simpler pasting chemistry. The process eliminates the complex basic lead sulfate reactions found in present methods.
